Large amounts of water may extract alcohol and affect cleaning performance. Therefore, to reduce alcohol loss, use desiccant dryers rather than water separators in the condensate return line. Contact with highly basic process materials, pH 10 or above, is not recommended.
Note: Test for compatibility before use.
Why Choose Miller-Stephenson Solvents?
Not all industrial cleaners have kept pace with the increasing demands for purity and regulatory restrictions in high technology industries. Miller-Stephenson’s MS-765/MS-767 Vapor Degreaser Fluid utilizes the most advanced, safest, and eco-friendly chemistry currently available. As electronic systems have become smaller and more complex, chemical purity has become even more critical. Today’s electronic components run hotter, are smaller and more complex than ever before. This creates situations where dendritic expansion or corrosion can proliferate if the cleaning is not perfect. Miller-Stephenson offers ultra-high-purity, non-flammable, and high cleaning efficiency solvents for a variety of industries and specifications. We offer VOC exempt and low or no GWP based solvent systems to meet all current and future regulatory specifications. From Electronic, Aerospace, and Military to Vapor Degreasing applications, Miller-Stephenson has the right solution for your specific application and requirements.
